This f invention *relates to an'- improved sash holder orloclr, and it has for one ot its principal objects',` to improve' upon the holder disclosed in Patent No. 1,097 ,1085k granted'to'me on May' l19, 1914.

The main `dierence between 'the ypresent holderk and the patented-one reside'sin al i novel and newl way of connecting the sash engagingjpawl to the stationary attachingu` member or channel and providingseparate and successively operable cani means between the -pawl and the channel' for effe/cting longitudinal ymovement ol:` the 'latter 5 with respect to the former when the' pawl ris moved downwardly b v the sashr when opening the window; and the' difference in'. operation brings about a newresult which -insures'a more effective rictional grip of the pawl on the sash.` lt' therefore follows that the present `holder is a kdecided improvement upon lmy patented one and other patented holders withy which l am familiar. Another object of the invention 'is to provide a holder of the Labove mentioned type which is simple in construction, such that after it is-once attached to asash the locking pawl will effectively engage the sash With which it coacts even if this sash moves slightly further away :troni the attaching member due to wear7 thus oveicoining the necessity 'of removing the' deviceto lchange its position to` accomplish the desired rcsult. f

A further object ot the invention is to generally 'improve upon devices ot this class by producing one oil extienie simplicity, which is highly ellicient in use, strong, duiable, and exceedingly inexpensive to manuvv facture.

More specicially speaking, it is animportant object of the invention to [devise a Window lock orholder of this class which embodies the aforesaid pawl and channelshaped attachingn meinhemthe lpawl being` Consequently', this action .f

@ther objects andadvantages of the in-y veiition'y vwill be apparent during of the following*v description.

In placing the ineinhei' in positiony vit ispre'l'erred that it he disposed transversely Aacross the sash inthe 4ina-nner clearly disclosed in the drawing. As betore'indicated', a locking pawl 2,-pre'icerably' made from a single' `metal stamping?- and provided with a rounded orcani tace 3 for lrictionial eng-agement with the upper 'saslfnl is conl nected with the*r attaching member.

such that a pair of oppositely disposed laterally extending base arms il are provided and these are disposed between the opposed vertical side walls or the attaching member and are niovably connected thereto. lt is with the attaching nieii'iber is not rigid is the case with the loclr disclosed in the aforesaid patent. i lt therefore follows that instead of rigidlyA connecting the pawl with the attaching ineriiber, l provide the latter in its side wallswith oppositely disposed' curved and elongated slots f5, the upper walls of which constitute cams and vact in a inanner to be hereinaiter 'described fr.- pivot and connecting pin is detachably connected with the narrow ends or -the aforesaid arins d and this pin extends through and is movable in said slot. lt might be saidthat such a construction provides a movable fulcrum for the pawl andthe slot permits the aforesaid longitudinal 'movement which is caused by the pin 6 riding againstthe upper curvedwalls of the slots.. This is one oit' the cam means hei'einbeorereferred to. ln order to cause the pin 6. to niove upwardly in the slot to bringabout this cam action, l provide a horizontally disposed pin '7 which -is extended through the sidewalls ot the attaching member gust below the slots and in advance `et these. This pin functions mainly as a tulcruin 'for the pawl, but is Vnormally ineilective and cornes into ,play

whe'nthe pawl is moved downwardly by the sash and is brought inte engagement there-` with. By carefully examiningthe rear portions of the lower edges o'lftliearins il.,

it will be seen that thesel are inclined as iiidicated at l0 and these inclined edges torni cams which act in advance of the aforesaid lllhile on the description oi this tule-ruin pin 7, l may point out that if desired, it may be mounted in sucha way that it is capable oi' rotation.

'Bv such an arrangement, it will -be seen that the engagement of the cam edges l() et the locking pawlwvill tend to automatically rotate it and in so doing, the points of contact between the cani edges and pin willbel constantly changed and naturally, thekliice -ot the pin will be greatly prolonged.

Although the force ot gravity would aution, it is desirablein this case, asin iny patented case,to"niove it to operative position by means ot a coiled spring` 8, this 'spring surrounding the fulciuin pin and having one of its ends anchored to one of the arins l and its opposite end bearing against-the abutment pin l' as better shownA iii Fig. o. Employment oit'this spring will assist in moving the pivot pin inthe kslot 5. An operating finger-piece will, of course7 be provided, this finger-piece being formed yin the same way that it is `formed in my patented device thatis, bv bendino' aA oition of oneor1 the arms 4l la erally as indicated ai' 8 and permitting this arm to extend beyonrlthe attaching member for convenient koperation.

ln use, the channel-shaped attaching meni- `ber is placed transversely across the lower sash in thev manner shown in. Fig. l, and

fastening screws are passed through aper- `tures in its y bottom tO secure it rigidly in Care should be taken in placing position. the attaching ineinber ink position that itis spaced away i'roin the upper sash just i'ar yenough to cause the tulcrum `ein of the locking pawl to seat in the lower ends or Anea-r the lower ends of the slots This exact positioning or parts' is not essentiah yupper sash and prevents ifurther movement Ot either oi the sashesl `llow, in case an attempt is made to open onej'or the sashes, the cani edges lllof the locking pawl will engage the pin Z and kin so doing will `cause the rear end ot the pawl to move upwardly. I -lt thereforefollows that the pin 6 nieves upwardly iii the inclined slot and the thrust exerted on the pawl by the downward nieveH ine-nt oit' the sash causesthis pin to engage the upperinclined edges `ot" the slots which function as eaiiisaiid compel the oawl 'to :move towardthe sash` and obtain a tighter and more eii'ective grip.

'l this point l wish to again call ttc lil 'uuu tion .to ythe tact that with this arrangement andy constuetion, the necessity of removing the attaching meinher and moving itch. .to the upper sash as Vas iound nece,r

with. patented device. diie to the i that the pas did not eifectively this sash when the latter becomes worn enough to increase the `space between itsell'I and the attaching member, is overcome. ,ln other l1 voids, the lockingl pawl of the present device will always move to properlv the sash Vwith which 'it co-acts, rdlcss oli whether or not this sash becomes From the 'foregoing description, it will be spacei'l4 slightly further away from the attaching ineinber than when the device was origi. nally attached to 'the window.

llO

seen that llliave .devised an extremely' ad- `vantageous sash holder which is a' decided improvement over my patented device and all other prior art, devices with which l ainr familiar, since it permits independent .lon-f ygitudinalniovenient of the locking pawl, which is necessary under ksoiiie circumstances.

l again wish to empliasizethe fact that such movement oi? the locking pawl causes the same to more effectively grip the sash in case either of them is moved to open posi tion. rllhe device is automatic in operation and the locking pawl can lbe easily swung out oip operative position topermit the sash to be easily and readily moved to open position. Furthermore, the construction and arrangement Awhich l employ is eXtrefi simple and inexpensive and is such that rthe parts `may be readily. disconnected lier replacement and repairing.`

rfi careful consideration or the foregoing talren in connection with the accompanying drawings will enable persons skilled inthe art to which this invention relates to obtain a clear understanding othesame, therefore, a more lengthy description of the use and advantages of the device is thought unnecessary.

Since probably the best results may be obtained with 'thev construction` arrangement disclosed, take this construction and arrangementv as the preferred embodiment t' my invention. However, I wish it to be understood that various minor changes in the-shape7 size, andarrangement of parts may be resorted to without departing Aitrom the spirit ci' the invention or lthe scope orthe subjoined claims.
